Abstract
A container which protects a book or similar product, has reinforced end walls and is easier and cheaper to form than present containers and the method of forming the container into a book package. The end protection cells of the container are attached to side reinforcing panels. This reduces the number of steps required to place reinforcing panels in the end wall construction. In the preferred construction the end cell panels are attached to the main body only through the reinforcing panels. In one construction, an additional bellows or gusset panel is provided for additional reinforcement.

A blank for a container comprising
- a first side panel,
- a bottom panel,
- a second side panel, and
- a top panel hingedly attached to each other by score lines,
- and a first closure panel hingedly attached to one of said first side panel and said top panel,
- bottom end members extending outwardly from end edges of said first and second side panels and said bottom panel,
- said bottom end members comprising
- reinforcing panels hingedly attached to said end edges of said first and second side panels,
- a central end section hingedly attached to said reinforcing members, said hinged attachment being score lines aligned with said score lines between said bottom panel, and said first and second side panels,
- said central end section being divided by transverse score lines into
- a bottom end cell panel having said hinged attachment with said reinforcing panels,
- an inner end panel hingedly attached to said bottom end cell panel, said inner end panel being separated from said reinforcing panels, and
- an upper end cell panel hingedly attached to said inner end panel.
